While it's been a low-level grumbling for years, the issue of Flash on mobile devices (and particularly the iPhone/Touch/iPad ecosystem) has reached fever pitch over the past few weeks, with Steve Jobs as self-appointed Flash basher-in-Chief. The OSNews crowd, that is, dyed-in-the-wool technologists have, by and large, not been big fans of Flash, with its spotty availability and performance on alternative platforms, resource hogging, and instability. And though it's quite useful for web video and other specialized interfaces, it drives the tech savvy crazy when it's used for utterly superfluous multimedia bling. So we've had a lively discussion of the pros and cons of Flash, and whether device users should be free to make their own decision about whether it's worthy to install on their iPads. But we're leaving out an important detail. As Daniel Eran Dilger, a Flash developer, points out, almost all the important existing Flash infrastructure won't work anyway.Update: A worthwhile rebuttal to this point of view.
